HYDRAULIC CIRCUITS

FUEL SUPPLY

The burner is fitted with a self-priming pump and two delivery
valves along the oil line from the pump to the nozzles.
The pump does not need calibrating, as it is set in the factory
at 12 bar; however, pressure level can be changed if necessary,
by adjusting the regulator fitted on the pump.
The delivery valves control the passage from starting to
operating phase.
At the start, after pre-purging phase, the first delivery valve
opens and the fuel is sprayed out through the first nozzle,
igniting when it comes into contact with the spark; then the
second delivery valve opens and the fuel is sprayed out
through both nozzles.
